In game analytics field, the game data mining has been recognized as one of the important tools to understand game players’ behaviors. It can help game companies predict players’ churn/retention or purchase behaviors from game log data. Although the game log data mining is so important in game AI community, there are few public datasets available to researchers and it limits the growth of the field. In this competition, participants can access to the big game log data recorded by NCSOFT, one of the biggest game companies in South Korea. This competition is officially approved by IEEE Computational Intelligence and Games 2017 (IEEE CIG 2017).

Competition Tracks

The goal of this competition is to predict the game players’ engagement to commercial MMORPG game from the massive game log data. Especially, the game has experienced the change of payment policy from fixed charge system to free-to-play. This competition will evaluate entries’ robust performance to make predictions on test datasets.

Track 1: Churn Prediction

In this track, participants will predict players’ churn or retention on the test datasets. The winner will be determined based on the average prediction accuracy.
– Evaluation method:

Track 2: Survival Analysis

In this track, participants will predict the survival time of game players on the test datasets. The winner will be determined based on the average root mean squared error.
– Evaluation method:
